The solenoid valve does not work after being energized
Check if the power wiring is bad → Rewire and connect the connector
Check whether the power supply voltage is within the ± working range - → adjust to the normal position range
Is the coil desoldered → re-soldering
Coil short circuit→replace coil
Is the working pressure difference inappropriate → adjust the pressure difference → or replace the appropriate solenoid valve
Fluid temperature is too high → Replace appropriate solenoid valve
There are impurities that make the main valve core and moving iron core of the solenoid valve stuck → clean them. If the seal is damaged, replace the seal and install a filter.
The liquid viscosity is too high, the frequency is too high and the service life has expired → Replace the product
